b) Consider the following TCP data transfer diagram: Host A Host B Timeout interval Timeout interval Seq=249, 40 bytes Seq=289, 60 bytes Seq=249, 40 bytes Ack 289 Ack=349 Ack=349 i) What is the new value of SendBase at Host A after receiving the Ack # 349? [1] ii) What will be the change in the given sequence if the second Ack (#349) comes before the first timeout interval? Draw the diagram with changes. [2] iii) If instead of first Ack (#289), first data segment (seq # 249, 40 bytes) is lost, what will be the Ack sent by Host B for the second segment (Seq # 289, 60 bytes) sent by Host A? [2]
